Abstract

The utility model discloses an automatic escalator or a pedal lock of an automatic pedestrian path, which comprises a lock shell, a lock core, a spring, a lock rod, a locking plate and an end cover, wherein an outer ring table of the lock core is matched with an inner ring table of the lock shell to stop, the lock rod passes through a hole of the end cover, the spring and a center hole of the lock core, a stop table on the lock rod is matched with the lower end surface of the lock core, the end surfaces of the lock rod, the lock core and the lock shell are parallel and level, the lower end of the lock rod is provided with the locking plate, and the spring is arranged between the lock core and the end cover. Because of using the structure, firstly, the lock core and the lock shell and the lock core and the lock rod are slidingly matched, gaps between the lock shell and the lock core and the lock rod are small, thereby being capable of preventing water, sand and dust from entering, popping up dust or water between the lock core and lock shell and the lock core and a top rod during the return process of the lock core, and being capable of effectively preventing a key from not opening a lock. Secondly, the lock rod, the lock core and the end surface of the lock shell are parallel and level, thereby being capable of effectively preventing form stepping, and causing error operation. Thirdly, the lock can be opened in an escalator, thereby being capable of rotating the top rod. Fourthly, the structure is simple, precision parts are not needed, and the making and the maintenance are convenient.

Description

The pedal lock of a kind of escalator or automatic pedestrian path

Technical field

A kind of novel staircase pedal anti-theft device is particularly locked at a kind of pedal of public traffic type staircase.

Background technology

Prior art generally adopts the mode of key switch or screw to prevent that escalator treadboards is stolen at present.These locking devices have following deficiency: 1, generally core is a strip, when being used for the public traffic type staircase, trampling for a long time and can bring a large amount of earth into lockhole, and causing maintenance is that key can't be opened.2. lockhole is a precision component, and it is stuck to be used for easily getting rusty when outdoor.3. adopt screw that pedal is fixed on form on the pedal frame, illegally reach real antitheft order ground.4. adopting bolt can't reach EN115-2008 requires: " the pedal lock can be opened internally ".

Summary of the invention

The objective of the invention is: the pedal lock of a kind of escalator or automatic pedestrian path is provided, and it is not only safeguarded simply, and waterproof, prevents trampling the sand prevention function.

The present invention is achieved in that the pedal lock of a kind of escalator or automatic pedestrian path, comprises lock housing, lock core, spring, locking bar, latch and end cap, and its special character is: the outer shroud platform of lock core cooperates stop bit with the interior ring platform of lock housing; Locking bar passes the centre bore of hole, spring and the lock core of end cap, and the stop bit platform on the locking bar cooperates with the lower surface of lock core; Locking bar, lock core are concordant with the lock housing end face, and the locking bar lower end is provided with latch; Spring is arranged between lock core and the end cap.

The pedal lock of described a kind of escalator or automatic pedestrian path, its special character is: the upper end of locking bar has along the axial key hole of locking bar.

The pedal lock of described a kind of escalator or automatic pedestrian path, its special character is: there is the hexagon blind hole upper end of the centre bore of described lock core, and the locking bar upper end is six prismatics.

The pedal lock of a kind of escalator of the present invention or automatic pedestrian path, owing to adopt such structure, the one, lock core and lock housing and lock core and locking bar are slidingly matched, gap between lock housing and lock core and the locking bar is little, can prevent that sealing, sand and dust enter, and in the process that lock core resets, the dust between lock core and lock housing and lock core and the push rod or moisture are ejected, can prevent effectively that key from can't unblank; The 2nd, locking bar, lock core are concordant with the lock housing end face, can prevent from effectively to trample, and cause maloperation.The 3rd, in staircase, also can unblank, only need to rotate push rod and get final product; The 4th, simple in structure, no precise part, manufacturing and easy to maintenance.

Description of drawings

Fig. 1 is a sectional view of the present invention.

Fig. 2 is the sectional view of user mode of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is further described.

As shown in Figure 1, the pedal of a kind of escalator or automatic pedestrian path lock comprises lock housing 1, lock core 2, spring 3, locking bar 4, latch 5 and end cap 6, and the outer shroud platform of lock core 2 cooperates stop bit with the interior ring platform of lock housing 1; Locking bar 4 passes the centre bore of hole, spring 3 and the lock core 2 of end cap 6, and the stop bit platform 41 on the locking bar 4 cooperates with the lower surface of lock core 2; Locking bar 4, lock core 2 are concordant with lock housing 1 three's end face, and locking bar 4 lower ends are provided with latch 5; Push rod and end cap articulate.Locking bar 4 articulates with end cap 6.

Spring 3 is arranged between lock core 2 and the end cap 6.

The upper end of locking bar 4 has along the axial key hole 42 of locking bar 4.

As another kind of embodiment: there is the hexagon blind hole upper end that also can be the centre bore of lock core 2, and locking bar 4 upper ends are six prismatics.

As shown in Figure 2, the present invention in use, lock housing is fixed on the pedal 7, the state among Fig. 2 is that pedal 7 is locked together in framework 8.

Key cooperates with key hole on the locking bar 4, and key promotes lock core 2 and moves down, and the top of locking bar 4 enters in the hole on the key, rotates key then, and locking bar 4 is rotated, and latch 5 rotates with locking bar 4.Latch 5 leaves framework 8.Extract key, then lock core 2 resets under spring 3 effects.

Above-described only is preferential embodiment of the present invention.Should be pointed out that for the person of ordinary skill of the art under the situation that does not break away from the principle of the invention, can also make some improvement and modification, this also is considered as protection scope of the present invention.
